USL-BI Taillight

Details

Serfas' versatile USL-BI Taillight shines both white and red LEDs so you can use it for the front or rear of your bike. Both colors run in three modes: high-beam, low-beam, and flashing. This USB-rechargeable light has an easy integrated bracket that clips on quick as well as an indicator light so you know when it's time to recharge.
